Does anyone know of source to obtain a cast iron ASME pressure vessel? The design and manufacture of the vessel would be the responsibility of the supplier - similar to a fabricated vessel.
chicopee, please further explain the annual legal inspections. If the air-oil separators of rotary compressors are not subject to annual legal inspections are the separators required to be constructed per ASME code VIII?
Maybe some further explanation of the receiver is in order. Oil-flooded rotary compressor systems utilize air/oil receivers for oil separation and recovery. In most large systems the air/oil receiver is separate from the compressor (connected by pipes, tubes, fittings, etc.). However, in...
What stress value (safety factor)is the required reinforcement area based on? My objective is to determine the safety factor when the actual area is less than the required area. Thanks for your help.
Does anyone has a definition of what makes a pressure container an integral part of a rotating mechanical device? If you encapsulate a rotating mechanical device is the container automatically excluded from code requirements?
Are the cast iron allowable stress factors - 10 for tensile, 6.67 for bending and 5 for compression - set to minimize permanent distortion? The factors for cast iron are considerably greater than those for steel (3.5 currently).
PVRV, Please elaborate on the caution regarding reflecting the hydrostatic pressure against the minimum yield value of the material, especially at 1.8xdesign pressure. How was the 1.8 factor derived? Are you suggesting that the proof pressure should be selected to ensure that the allowable...
What is the purpose of a hydrostatic test conducted at 1.3 to 2.0 times the maximum allowable working pressure? Is this primarily a leak test? Does this pressure validate the structure integrity of the component? Your opinions, comments and intrpretations are most welcome.

We are investigating the use of a swing check valve to control reverse flow at an air compressor inlet. A swing check valve was chosen to minimize flow restriction. I am under the impression that swing check valves offer the least resistance due to the straight flow path. I am concerned that...

how do you determine the fuild force on a swing check valve plate for sizing of an acutator? are there any informative sites available? Thanks for the help.
